In this episode's challenge, Jason and Suzi go head to head in a competition to produce the best cinema trailer. With cutting-edge amateur recording equipment at their disposal and acerbic Radio 1 film critic James King judging, the stakes are high. While Jason discovers an astonishing camera capable of filming in 360-degree wraparound vision, Suzi opts to embrace the 3D fad. Suzi makes the potentially risky decision to build her own camera system, but she scores a coup when she lands the world’s only ‘emotion jacket’, designed to allow viewers to share in the intense sensations experienced by on-screen characters. Elsewhere, Ortis looks into the murky world of black ops warfare and top-secret research projects. Top of his list is the Little Dog project, run by the US military’s secretive DARPA (Defense Advanced Research Projects Agency) arm. The Little Dog is an incredibly advanced four-legged robot capable of giving chase to targets over rough terrain. Can Ortis persuade the creators to divulge the secrets behind this awesome new technology? Meanwhile, in Singapore, Jon and new girl Pollyanna road test the team’s top five in-ear headphones. Pollyanna soon finds herself being catapulted 200 feet in the air at 125mph on the end of a bungee rope – all in the name of research. Finally, Jon dons his whites and ventures into the kitchen with top chef Jean-Christophe Novelli to try out three of the best dishwashers on the market. But will any of the timesaving devices live up to the fiery Frenchman’s high standards?
